Embodiment
Further describe technical scheme of the present invention below, but described in claimed scope is not limited to.
One machinery Ride Control System as shown in Figure 1, comprises keyboard, coding unit, transmitter unit, receiving element, decoding unit, decoding unit, CPU (central processing unit) and performance element; The signal output part of described keyboard is connected with the signal input part of transmitter unit by coding unit, wireless connections are passed through between the signal output part of described transmitter unit and the signal input part of receiving element, the signal output part of described receiving element is connected with the signal input part of CPU (central processing unit) with decoding unit by decoding unit successively, and the signal output part of described CPU (central processing unit) is connected with the signal input part of performance element.
The master chip of described CPU (central processing unit) is AT89C51 single-chip microcomputer.
The chip that described coding unit adopts is PT2262.
The chip of described decoding unit is PT2272.
The chip of described decoding unit is CD4514.
The master chip of described performance element is ULN2003A
As shown in Figure 2, described keyboard has 13 buttons, except reset key and remote control extension spare key, the combination that all the other 10 buttons control mechanical clutch respectively be separated, the lifting of bearing circle and decline, left and right turn, high and low shift switching etc.; Keyboard is connected to coding unit, and described coding unit take PT2262 as core, is encoded by input signal; Described coding circuit unit is connected to wireless transmitting unit module, and transmitter unit is by signal madulation and adopt the frequency of operation of 315MHz to send.Concrete employing principle of work is: in time having button to press down, different buttons will make the input port D0 of coding chip PT2262, D1, D2, D3 obtains corresponding low and high level signal, transmit signals to transmitter unit by the output port Dout of coding unit, then by transmitter unit, this group numeric data code and address code are sent.Meanwhile, can provide operating voltage by diode to coding chip and transmitter unit when button is pressed, transmitting indicating lamp DS1 lights.
The circuit diagram of receiving element as shown in Figure 3, decoding unit and decoding unit.Receiving element restituted signal again after mainly carrier signal that receiving antenna senses being amplified, is reduced to original control signal, is transported to CPU (central processing unit) and carries out analyzing and processing.Receiving element is made up of parts such as frequency selection circuit, high-frequency amplifier circuit, detecting circuit, low-frequency amplifier circuits, after antenna receives carrier signal, the signal of 315MHz is selected by frequency selection circuit, amplify through high-frequency amplifier circuit again, original low frequency signal is detected by rectified signal, filter carrier signal, the signal exported after low frequency amplifies sends into decoding unit; Described decoding unit is based on chip PT2272, and decode effective output port D0, and D1, D2, D3 will export corresponding low and high level, then signal carries out decoding by code translator CD4514 after TLP521-4 carries out light-coupled isolation, and deliver CPU (central processing unit).
As shown in Figure 4 and Figure 5, described CPU (central processing unit) take AT89C51 system as core, mainly analyzing and processing is promptly and accurately made to the remote signal received, and compare with the signal that sensor feedback is returned, make corresponding response, control the action of each solenoid valve, make mechanical remote control control loop can by telecommand work.
After receiving remote signal, from 13 passage decodings remote signal out of coding chip CD4514, Y9, Y10, Y11, Y12, Y13, Y14, Y15 are imported in CPU (central processing unit), by the process of CPU (central processing unit) single-chip microcomputer, the control signal of output will control left and right turn, the high and low shift switching of machinery respectively and reset.
Specific works process: Y9, Y10 meet the P1.4 of single-chip microcomputer, P1.5 port is end for subsequent use.Y12, Y13 is left and right turn input signal, when single-chip microcomputer receives left-hand rotation or right turn signal, first export the signal of lifting bearing circle, after being put in place by the lifting of executive circuit control bearing circle, signal feedback in single-chip microcomputer, is exported go to action signal by the digital hall sensor of detection bearing circle lifting.Putting in place when having turned to, detecting the sensor that turns to by signal feedback to single-chip microcomputer, then bearing circle is fallen.Y14, Y15 is gear shift input signal, when single-chip microcomputer receives gear shifting signal, first output clutch separation signal, after being completed by actuating mechanism controls, sensor feedback is returned separation and to be put in place signal, then exports gear shifting signal, single-chip microcomputer output clutch binding signal again after sensor detection gearshift completes, completes whole shift process.Y12, this 4 road signal of Y13, Y14, Y15, except meeting single-chip microcomputer P1.0, P1.1, P1.2, P1.3 port carries out outside left/right rotation and high and low shift identification respectively, and after the not gate 74HC04 that respectively hangs oneself, input and door 74HC21 connect single-chip microcomputer INT1 interruptive port, when requiring to turn to or shift gears, are performed by external interrupt request.The signal Y11 that last remote control resets directly deliver to after not gate 74HC04 priority the highest in fracture INT0, when a failure occurs, directly can be resetted by telepilot.
The remote signal sent by keyboard, after CPU (central processing unit) carries out analyzing and processing, outputs signal the control circui topworks action by performance element, makes machinery by remote signal work.Its workflow is: from coding chip CD4514 decoding all the other 6 road signal Y1 out, Y2, Y3, Y4, Y5, Y8 and from single-chip processor i/o port control signal out, light-coupled isolation is carried out by TLP521-4, to reduce the interference of electromagnetic relay to CPU (central processing unit), then after ULN2003A drives, control pneumatic actuator by relay group.When control signal output is 1, then relay adhesive, corresponding topworks's power supply is connected, and performs corresponding action.From the coding chip CD4514 decoding signal out of remote control reception part, turn to except gear shifting signal except what send central processing unit for processing, Y1, Y2 signal controls bearing circle lifting, and Y3, Y4 signal solenoidoperated cluthes are separated and combine, and Y5, Y8 regulate tilling depth.Because of single-chip processor i/o port P2.0, P2.1, the signal that P2.2, P2.3 export also is control bearing circle lifting and clutch separation, combination, thus by its respectively with the signal Y1 of direct remote control, Y2, Y3, Y4 are in parallel, and arbitrary output signal is 1, all can control corresponding relay adhesive, relay coil institute also diode is fly-wheel diode.Described relay K 1, K2 controls bearing circle lifting, and K3, K4 solenoidoperated cluthes combine and are separated, and K5, K6 control left and right turn, and K7, K8 control gearshift, and K9, K10 control job status.
The actual property of this design on control circuit is simple to operate; stability is strong; remote control distance is far away; effectively can realize remote control during mechanical work; and raise labour productivity, reduce labour intensity, improve work quality; and the technical barrier such as working environment and safety condition of operator can be improved, and new period agricultural machinery scale of operation, specialized Production requirement can be met.
